Odaily News Blockchain infrastructure provider RISC Zero and Celestia are collaborating to build Blobstream Zero, a zkVM-based Blobstream bridge. Blobstream Zero aims to connect Celestia's data availability layer with chains such as Ethereum, Optimism, Bitcoin, Solana, and others. Blobstream is Celestia's solution that enables Rollups to leverage Celestia light clients for data availability sampling. Blobstream Zero introduces the ability to verify Celestia DAs using zero-knowledge proofs. The integration allows Rollups and applications to generate proofs across chains more efficiently. Blobstream Zero also introduces a ZK coprocessor that enables DApps on Ethereum, Optimism, and Solana to run data-intensive ZK programs without sacrificing composability. Blobstream Zero will be a fully open source and permissionless public product. This means that all developers and projects can run Blobstream Zero and generate ZK proofs locally.
